FLEXIBLE INDEX STRIP.

Original application filed July 14, 1922, Serial No. 574 913. p 1926. Serial No. 120,020.

5 in flexible index strips and refers more particularly to flexible strips which may be mounted in a frame upon which data is placed Where the file is of a relatively temporary character.

Among the objects of the invention are to provide a construction in which flexible line strips are provided in the form of a sheet, and the sheet so scored that the line strips may be easily-separated from the sheet by tearing along the scored separations. To provide a construction in which the sheet may be inserted in a typewriter to write any desired data upon the strips rior to separating the strips from the sheet. to provide a flexible line construction -which when separated from the sheet may be doubled in order to foreshorten their length and snapped into place behind flanges in a suitable frame.

Fig. 1 is a face v'ew of the frame showing the str'ps in position. Fig. 2 is a fragmentary face view of the strips in the form of a sheet prior to the strips being separated. Fig. 3 is a view taken along the line 33 in Fig. 2. Fig. 4 is a perspective view of one of the strips after being separated from the sheet.

Referring to the drawings. the frame 1 consists of a body of metal which has along its lateral edges flanges or lips 2 extending longitudinally of the frame and riveted to the body portion. The frame is supported in a suitable standard by means of the pintles 3. In Fig. 2 is shown a sheet of strips prior to separation.

The sheet comprises a thin ply or layer Divided and this application fild July 2,

of Wood veneer faced on both surfaces by a sheet of paper or fabric. The sheet is cut transqersely to form line strip 4 as that shown in Fig. 4. In cutting the sheet, the

cut is made through one surface and through the wood veneer leaving the paper upon the opposite surface intact. This sheet may be wound on the platen of a typewriter, and dentifying data put upon the separate strips. Upon removal from the typewriter. the strips may be torn from the she-ct singly, or in numbers, and inserted into the frame by doubling the flexible strips and inserting there'n beneath the side flange 2 on the frame.

Strips of this type are easily removable when a change of the data is desired, by inserting an edge beneath the strip and withdrawing its ends from the side flanges of the frame. I

The wood veneer with the paper surfacing glued thereto, furnishes a cheap and eifective material which takes the print readily and presents a smooth uniform face to the indexing frame. The frames are reversible. and a plurality of frames may be mounted upon a single standard.

I claim as my invention 1. Separated flexible index strips comprising strips of wood faced with a sheet material which will take print readily.

2. Separated flexible index strips comprising strips of wood faced and backed with a sheet material which will take print readily.

Separated flexible index strips comprising strips of wood faced with paper.

4. Separated flexible index strips comprising strips of wood faced and backed with paper.
